IV drug use/rash day after
so my dumb ass decided to shoot up some cocaine and i am terrible at doing it, and i could not hit except for once. ended up plugging it (rectal). anyway, the day after shooting, in the morning, everything was fine except track marks. then later that day a rash 4 inches above where i had injectected, over to the side even, not even sure if its over a vein but its on my fatty muscle on my arm, and its like an half inch long with a 3cm straight line coming from it. i marked the edges of it with a pen and it did not grow at all and it seemed to have healed a bit. its only been a day. i feel completely fine and everything and there are no other marks and it doesnt seem to be spreading. there is no pain, yesterday when it initially showed up it kind of hurt because it was an open sore. once again this isnt near the injection point, but its so random. is this safe/does anyone know what this could be? i am traveling and have no money so i cant afford the hospital
also on the one shot that worked, my right hand got super hot and numb for like a minute or two. the track marks have healed over and i guess if the little soar doesnt go away ill do something about it. but is there any underlaying sneaky bacteria that could kill me/make me loose a limb that i wouldnt have had any issues with yet??
